SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 417,285, dated-December 17, 1889.

Application tiled May 7, 1888. Serial No. 273,104. (No model.)

To all whom it may concern:

Be it known that I, ALBERT ROSA, of Milwaukee, in the county of Milwaukee, and in the State of Visconsin, have invented certain new and useful Improvements in Sad- Irons; and l do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to that class of sadio irons that are made hollow and heated by` burning charcoal placed therein, being an improvement on the iron shown in my Patent No. 369,556, dated September 6, 1887, said invention consisting in certain peculiarities of i 5 construction and combination of parts to be hereinafter described with reference to the accompanying' drawings and subsequently claimed.

In the drawings, Figure l represents a side zo elevation of a sad-iron constructed according to my invention; Fig. 2, a rear elevation, part-ly in section, on line 2 2, Fig. 4; Fig. 3,a vertical longitudinal section on line 3 3, Fig. 2; Fig. 4, a horizontal section on line a 4f,

Fig. 3; and Fig. 5, a detail plan view of a portion of my iron.

Referring by letter to the drawings, A represents a hollow shell that forms the body portion of a sad-iron constructed according 3o to my invention, the'under side of the shellbottom being finished to serve as a smoothing-face. The bottom of the shell A has a rearward extension a, that is rounded off to serve as a polishing-edge, and has an up- 3 5 turned ange or guard b to prevent loose play of a'slotted guide-plate B, that is pivoted to the rear end of said shell to cover an opening c therein. Arranged on the plate B i is a slide C, that is provided with slots d to 4c be brought in or out of register with the slots in said plate, said slide being provided with a handle e, by which it may be moved back and forth and the plate B swung up or down on its pivot.

The opening c in the rear of the shell A serves as an outlet for ashes that may accumulate in said shell while the iron is in use, the plate B being swung up on its pivot to uncover said opening, and then by holding the iron at an angle and giving it a slight shaking movement the ashes will be readily discharged.

Hinged to the rear end of the shell A is a cover-piece D, the vlatter having its edges 7 preferably provided with a series of depend- 55 ings lugs f, that terminate near the adjacent edges of said shell when the cover-piece is in its normal position, the aperture g between these lugs serving as draft-openings; but, if found desirable, l may omit the lugs and have 6o a single longitudinal opening in place of the apertures, said lugs being more particularly designed as guards to prevent escape of sparks from the burning charcoal. rlhecover-piece D is kept down in place by means of aplatch E, that is pivoted to said cover-piece, and engages a notched lug 7i, projecting up from the front end of the shell A, the latch being provided with handle i, in which is arranged a spring-plunger j, that automatically engages 7o a notch' j on said cover-piece to hold said latch in engagement with the lug z, said notch being beveled to permit a ready disengagement of the plunger j; but it is obvious that other suitable mealis may be em- -7 5 ployed for holding the latch in engagement with the lug.

To the underside of the cover-piece D, l detachably connect a plate F, and by means of this plate the weight of the iron may be So varied. The main portion of the iron is made to a standard weight, this weight varying according to the dimensions of said iron, and a plate F, also of a standard weight, is designed to accompany each iron. Now, if the iron should be too heavy, its weight may be decreased by the substitution of alighter plate, and if too light a heavier plate would be substituted, the weight of these plates being graded to suit the requirements of the trade. 9o

At the center of gravity of the iron the cover-piece D is provided with a rise 71;, that has a beveled longitudinal recess 7o, that receives the correspondingly-shaped shank m` of a handle Gr, said shank being provided with a screw-threaded extension in', that passes down through said cover-piece and receives a washer n and set-nut o, that holds the handle against vertical displacement, while at the same time the recessed seat for roo lthe shank of said handle prevents any pivotal movement of the latter.

Near the bottom each side of the shell A is provided with a longitudinal slot t-hat extends from heel to point of the iron," and detachably connected to said sides of the shell, so as to enter said slots and come flush with the outer sides of said shell, are plates II, provided with draft-openings p, those shown being continuous in a longitudinal direction; but, if found desirable, a series of perforations may be substituted, this variation being obvious. In the preferred form of my iron the plates I-I'are of such width and are so arranged in the slots in the sides of the shell A that longitudinal draft-openin gs gare left above and below said plates, the latter openings and the ones p being narrowed toward the inside to prevent the escape of ashes and coals when the iron is in use.

While I have shown the detachable plates H, it is obvious that the same may be omitted'l and the draft-openings p q cut or otherwise made in the sides of the shell A; but as the greatest amount of heat comes against that portion of the shell adjacent to said draftopenings the metal is liable to warp or burn out, and in such a case the iron would be worthless or expensive to repair; but by having the detachable plates Il this difficulty is obviated, for the reason that should these plates warp or burn out they can be readily replaced by new ones at a tritling cost. The ends r of the plates II overlap the adjacent sides of the shell A, and each of these plates is centrally provided with a strengthening strip or web s, that also overlaps the sides of said shell. serves to brace the sides of the shell, and thereby strengthen the latter, especially as I prefer to make said shell of cast-iron and said plates of' wrought-iron, steel, or other suitable material having greater strength and durability than the cast-iron.

In each side of the shell A, above the plate I-I, there is a vertical slot t, and passed through this slot is the stem u, that is surrounded by a spiral spring v, the latter being inclosed by a thimble w and arranged to exert its force against a washer cc, that is slipped on said stem between the said shell and thimble.

To the inner end ot' each of the stems it, I connect a damper I, for the purpose of opening or closing one, two, or all of the openings p q in the adjacent side of the shell A at the will of the operator, the damper being held in the position to which it may be adj usted by the`friction of the spring-controlled washer against said side of the shell. As shown, each vdamper is cut away in the center to engage the web s on the adjacent plate II, this web and said cut-away portion of the damper bcing dovetailed to each other as a means for securing a uniform movement of said damper throughout its length; but other suitable means may be employed for the same purpose. At the ends each'damper is offset, as shown This construction of the plates IIl at y, to overlap and slide on the ends lr of the adjacent plate II, these ends of the plate serving as guides for said damper in its vertical movement.

In the operation of my invention the shell A is filled with charcoal and the latter ignited, the dampers I being opened to obtain a circulation of air through the mass. to keep the latter in a state of combustion, the area of the draft-openings being proportioned to the size of the iron, so as to obtain uniform combustion throughout the entire mass of fuelavhereby the latter burns evenly and said iron is uniformly heated. The air enters through the openings p q and ascending through the mass of fuel in t-he iron passes out through the apertures or openings g between the coverpiece D and the adjacent edges of the shell, and at the same time there is a horizontal draft through the opposing apertures or openings g over the fuel, and consequently7 the whole mass kindles rapidly and burns evenly, thereby preventing' smoke and gases that arise from imperfect combustion. To regulate the heat, the dampersIare adj usted to open orelose one, two, or all of the openings p q in the shell, and in case all these openings should not be of ksufficient area to obtain draft enough the slide C on the rear plateBis adjusted to bring its openings d in to register with those in said plate, this being requisite at times to cause an even combustion of that portion of the fuel in rear of the openings in the sides of the shell. Then the iron is not needed for use and it is desirable to economize the fuel, the dampers I are adjusted to close all the openings p qin the sides of the shell A, and should there not be sufficient draft through the opposing apertures or openings g to keep the fuel ignited I adjust the slide C to permit entrance of air through the rear opening at the lbttom of said shell, thus securing enough draft to keep the [ire alive and burning slowly for an indefinite time, thus saving the trouble of relighting when the iron is again put in use, it being only necessary to raise the side dampers in order to have a quick hot fire in said iron.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Ahollow sad-iron having each of its sides provided` with a bottom openinga plate of less width than said opening detachably 1itted therein, and a damper for the space between the plate and adjacent edge of the opening, substantially as set forth.

2. A hollow sad-iron having each of its sides provided with a bottom opening, a plate detachably fitted in the opening to leave an upper and lower space, dampers for closing said spaces, and draft-openings arranged in said sides at the top of the iron, substantially as set forth.

3. A hollow sad-iron having each of its sides provided with a bottom opening, a plate detachably fitted in the opening to leave an upper and lower space and provided with cen- IOO IIO

tral draft-openings, dampers for closing said spaces and the openings in the plates, and draft-openings arranged in said sides at the top of the iron, substantially as set forth.

et. A hollow sad-iron having each of its sides provided with a longitudinal opening near its bottom, a plate of less width than the opening iitted therein and provided with a dovetailed web, a damper arranged to slide on the web, and draft-openings arranged in said sides at the top of the iron, substantially as set forth. I

5. A hollow sad-iron having each of its sides provided with a central vertical slot and longitudinal bottom openin g, a plate of less width than the opening iitted therein and centrally provided with a web, a damper for the openings cutaway to engage the web,`a stem secured to the damper and arranged to extend through the vertical slot in the adjacent side of the iron, a washer arranged on the stem to impinge against said side of the iron, aspiral spring surroun din g said stern to exert its pressure against the washer, and a thiinble surrounding the spring, substantially as set forth.

6. A hollow sad-iron provided with a cover having a weight-plate detaehably connected thereto, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set iny hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
